Hi, I bunked my head earlier on a car as I was getting in. It barely hurt and the pain went away very quickly. I ve been having a constant dizzy feeling ever since. The dizziness only lasts a few seconds and then goes away and comes back a little while later. When I leaned back the look at the ceiling, the room started spinning. I also feel some pressure in my head, but it has dulled down a little. I will also add that earlier today before the incident, I had some faint, sharp pain in my neck when I moved it a certain way. This also went away quickly and only occurred twice. Could this be related to my dizziness? Is it serious? Is it dangerous to go to sleep?
